Definitions

  • This invention relates to homogeneous enzyme-containing liquid detergent compositions containing substantial levels of saturated fatty acids. These compositions provide a series of remarkable stability benefits in respect to both functionality optimization of the individual ingredients and physical stability of the composition. More particularly, the compositions of this invention unexpectedly provide the cumulative benefits inherent to the presence of the detergent enzyme and to the substantial level of the saturated fatty acid.
  • enzyme-containing liquid detergent compositions require the presence of certain minimum levels of calcium as a primary stabilizing agent. This is especially applicable for proteolytic and amylolytic enzymes.
  • the liquid enzymatic detergent compositions of the prior art containing substantial levels of fatty acids and/or soaps are deficient with respect to important product characteristics.
  • the minimum level of calcium needed to provide acceptable enzymatic stability induces precipitation (in the liquid composition) in presence of substantial levels of saturated fatty acids and/or soaps.
  • the like shortcomings can be overcome with the aid of known formulation changes inclusive of lowering the calcium level. or using substantial levels of soluble calcium sequestrants. Both approaches can not be used in the context of this technology.
  • the elimination or the substantial reduction of the calcium yields enzyme deactivation and instability upon aging. While the incorporation of strong sequestrants effectively cures the product instability, concurrently, it yields a substantial lowering of the enzymatic activity.
  • Earth alkali-metal salts inclusive of calcium chloride, calcium acetate, magnesium chloride and magnesium acetate are recommended for stabilizing the enzymatic activity.
  • Concentrated enzyme containing alkaline liquid detergents are also known from French Patent 2,369,338.
